The Urban Dictionary T-Shirt

An issue within a relationship that constitutes one partner breaking up with the other. Note that they do not need to be a "good" reason by society's standards, but are specific and individual to each relationship.

Some aspect of a deal you make with another person (could be anything from a job offer to a relationship) that prevents you from being able to do it.

When you're facing a situation where there are catches to something, the deal breaker is that one catch that you cannot overlook and/or tolerate.

After looking at this job offer, I could tolerate the lousy shifts, poor pay and even the job being not that great. Having to put up with a two hour drive two and from work every day? Sorry but that's the deal breaker.
